Note: when you refer commits, write at least 12 first characters of the commit's hash. You may want to set `core.abbrev=12` in your `~/.gitconfig`. Also the canonical commit reference is `--pretty=format:%h (\"%s\")`. And remember: when replying, don't top-post; reply inline with appropriate context instead. Anyway, I'm fixing up the title: #regzbot title: Realtek ALC236 unrecognized on reboot Thanks. -- An old man doll... just what I always wanted! - Clara
